computer.

to run on a monthly schedule, but you can defragment your computer manually at any time.

Using HP 3D DriveGuard (select models only)

HP 3D DriveGuard protects the hard drive by parking the drive and halting data requests under either
of the following conditions:
● You drop the computer.
●
You move the computer with the display closed while the computer is running on battery power.
A short time after the end of one of these events, HP 3D DriveGuard returns the hard drive to normal
operation.
NOTE: Because solid-state drives (SSD) lack moving parts, HP 3D DriveGuard is unnecessary.
NOTE: Hard drives in the primary hard drive bay or in the secondary hard drive bay are protected by
HP 3D DriveGuard. Hard drives installed in optional docking devices or connected to USB ports are not
protected by HP 3D DriveGuard.
